Treatment of 2-ethylamino-2-methylpropanol oxime with aryl isocyanates leads to 4-N-(arylcarbamoyl)hydroxyamino-1-ethyl-3-aryl-5,5-dimethyl-2-imidazolidionones, which are acylated by acid chlorides and methyl isocyanate to give the corresponding O-acyl derivatives and are converted to 2-(2-oxo-1-ethyl-3-aryl-5,5-dimethyl-4-imidazolidinyl)-4-aryl-1,2,4-oxadiazolidine-3,5-diones by the action of methyl chlorocarbonate.
